species as P. suberosa and P. biflora. The indument, the cutting of
the bracts, and the size and color of the flowers and fruit are remarkably
constant.
The degree of correlation of the characters varies, of course, in
the different varieties of P. foetida. In general, it may be said that
varieties which are glabrous, or nearly so, throughout have bluish
or pinkish flowers and large, red fruits, whereas the presence of a
strong indument is correlated with white flowers and smaller, yellowish
fruits. As the major subdivision, however, I have taken the
presence or absence of hairs on the ovary. The varieties, on the
whole, fall into four main groups, as follows:
(1) Plant often quite viscous; stem pilosulous or hirsute with
white, grayish, or yellowish hairs; leaves lanuginous-hirsute; bracts
deeply 2-3-pinnatisect, but the ultimate filiform segments not closely
interwoven or matted; flowers white, of medium size; ovary densely
pubescent; fruit relatively small, yellowish, pubescent, though sometimes
the indument scant.
(2) Similar to No. 1, but the indument usually less dense, sometimes
wanting, the ovary always glabrous.
(3) Similar to No. 1, but the segments of the bracts closely interwoven,
the indument of the vegetative parts consisting of long,
yellowish hairs, the ovary being glabrous.
(4) Plant usually glabrous, except for a few gland-tipped hairs
on the stem, petioles, peduncles, and leaf margin; flowers blue,
purplish, or pink, rather large; fruit more than 3 cm. in diameter,
red or scarlet.
For convenience, I have prepared three keys to the varieties,
based on the three major areas of distribution, i.e., southwestern
United States, Mexico, and Central America; southeastern United
States and the West Indies; and South America. The sequence in
the text, however, indicates their probable relationship.
Passiflora foetida is reported to be used for head colds in British
Honduras. The fruit is eaten in many countries. Local names
applied to the typical form or to the varieties are: "Clavellin bianco,"
"injito Colorado," "flor de granadita," "ke"-pa" (Mexico); "granadilla
colorada," "granadilla months," "granadilla silvestre," "sandia de
culebra" (El Salvador); "bombillo" (Costa Rica); "caguajasa,"
"canizo," "cuguazo," "granadilla cimarrona," "pasionaria hedionda,"
"pasionaria de la Candelaria" (Cuba); "love-in-a-mist" (Jamaica);
"Mariegouya," "toque molle" (Haiti); "tagua-tagua" (Puerto Rico
